First off I'm not sure what a Rotate Dial is actually called. I am thinking of something similar to a HeroClix base (a rotating top piece with a hole, which reveals different stats on the bottom piece as it rotates), but I'm trying to make them out of cardboard. So a 2 circle pieces of chipboard, one with a notch cut out, and somehow attached.
I was thinking I can attach them together with a plastic (or metal) rivet. However since my pieces are smallish ~1.5in, I'm having a hard time finding a small enough rivet.
Is there a name for this?
Is there a known good way to make this thing?
